Gauging interest in Ti valves?

Gauging interest in Ti valves?
So awhile ago I ran this thread over on cr and learned that most guys over there are not super big spenders in the engine department. Now I ask you guys, is there any interest in buying a set of Titanium Valves with BeCu Valve Seats.
Now, this is just looking to see if anyone would be on board. Okay, so for the long part, I asked a guy if he could make me some valves. He said he could but I would have to buy at least 40 seats. I can have as many valves as I need. So I got quotes as if I had 4 other people come in on them with me.
So the quote:
40 intake $97.75 each
40 intake seats $17.50 each
40 exhaust $100.25 each
40 exhaust seats $17.50 each.
Now this is subject to change, but all I am doing is seeing if people would even think about this.

I find it hard to believe that it costs that much to convert over to Titanium. Not saying my statement is valid, but damn. Have you consulted with other valve train manufacturers?
It is something I had contemplated, but thought it was out of reach for me, so I never looked into it. I am curious as to how much gain this modification would net.

It lightens the top end weight and makes the engine more rev happy. They are stronger than stainless valves. Lastly the instant throttle response is even crisper. Which is perfect for me.
Long term goals, lightened flywheel and pulleys, stroker kit, irtbs, supercharger, 6 speed, and even more... all in the search for instant pedal feel.

That is a lot of money to put up front.

Going Ti valves would be pretty long down on the prio list and with my logic only be interesting for the 4th or 5th engine trying to squeeze the last out when faced with a regulation making it "worth it".
Going that deep into a build have IMHO nothing to do with of the shelf "goodies" regarding any part involved in the airflow (OK, ST valves are OTS and good enough for a lot of engines, unsure about exhaust for high boost though).

There is but 1 or 2 people on this whole forum, of which you are 1, that are stupid enough or silly enough to spend 2k on valves.
We boost our cars because its the most bang for the buck. We drive lowly BP's, and anyone stupid enough to sink that kinda cash into an n/a or supercharger build just hates himself or is really that dumb, or is so rich and ballin that they can't think of more challenging ways to throw away money.
And comments like this:

Are going to get you laughed off the forum.
Good luck with your 40 sets of valves, or 5 extra heads or whatever. I hope you're prepared to lose a ginormous chunk of money "in the name of science" lolol

Most valve manufacturers don't recommend Ti for boosted applications because they retain heat better than steel. Most manufacturers also recommend Beryllium copper seats and valve guides to guarantee long valve life. Plus beryllium is toxic when aerosolized so some machine shops won't cut the valve seats. There are other companies that make copper alloys with out beryllium but they are still expensive.
The problem as stated above is that the bp isn't a high revving unit and outside of drag racing the turbos most of us use run out of steam before the benefits of a marginally lightened valve train would be effective.
You might look into other custom features like hollow valve stems in steel valves to reduce valve weight as a more cost effective and boost friendly solution

I don't get why. I understand you daily drive your car, right now so do I. But I plan on building a full on race car for the track. So when I drive my *** off, I like to know that what I built will stay together. I don't want to spend a "ginormous chunk of money" but if the situation arises I have no problem doubling my buying price of the valves and seats.

I see a special kind of irony in someone who's stupid enough to purchase a C5 automatic criticizing the automotive purchasing choices of others

And since we're on the subject: why don't you please please please tell me what's wrong with a daily driver c5 auto?
If I was spending 10k on an engine, it would be an LSx or f20c or something, not a bp. Like you said, different strokes, but when you can have a lot more power with the same reliability for almost the same money I'll take that option.

Even proper grade Ti have poor wear characteristics and I would suggest checking regularly (every 10 race hour at least).
Yes there are Ti in production vehicles, but you would then assume that they have freedom with every related part (design spring rate/pressure as they wish), not just slam it in there and add the next available spring just to make sure.
Tear it down every 8-10 hours, fine, then you know what you are doing and can judge the benefits yourself.

To the guy who said stay away from Ti valves: What you say has a valid point but (and this is a big but) I am not looking to do the stuff to the valves that causes failure. No turbo (at most a supercharger with low psi) and all the proper supporting mods to back it up ie. ti retainers, becu seats. Now am I saying that they will go without failure? No, I know how they can fail and why they do, so maybe that could help me make mine last way longer.
And if this option ends out being way too expensive, I will just take my time finding a 323 gtr head with it's better airflow and sodium valves (even though they aren't oversized) and go with that path (which I would still build the valve train and the cams to the spec I needed). Who knows.
